This article describes the ACE appliance physical Gigabit Ethernet (GE) ports and how to troubleshoot port-related issues. Note that the ACE module has no external ports of its own and it relies on the back plane of the Catalyst 6500 series switch for communication with the rest of the network.

Configuring a Port Channel

You can assign VLANs directly under the physical interface or using a channel group. These can be trunked or access ports. For trunked ports, the default native VLAN is 1, which can you can change by entering the switchport trunk native vlan number command under the physical port or a channel group.

The following example shows how to configure a port channel in the ACE appliance:

By default, the load-balancing scheme is source-dest-mac. You can change it to destination-ip, destination mac, and so on using the port-channel load-balance command.

Troubleshooting Port Channels

If the configured VLAN or BVI does not come up, verify that the assigned port-channel is up and that it is configured correctly on the 3750 or Catalyst 6500 series switch, and check the physical ports.
